The most basic form of ACC theory states that the ACC is involved with error detection.[4] Evidence has been derived from studies involving ...

Anterior cingulate cortex (ACC): the frontal part of the cingulate cortex that resembles a "collar" surrounding the frontal part of the corpus callosum; plays a role in a wide variety of autonomic functions such as regulating blood pressure and heart rate; also involved in rational cognitive functions, such as reward anticipation, decision-making, empathy, impulse control, emotion

People with PTSD are shown to have 2 areas of the brain that are sensitive to STRESS SHRINK: the hippocampus,in the limbic system important for memory & the anterior cingulate cortex, part of the prefrontal cortex that is involved in reasoning & decision-making. A fMRI, which tracks blood flow in the brain, revealed that when people who have PTSD are reminded of the trauma, they tend to have an underactive prefrontal cortex & an overactive amygdala, which processes fear and emotion.

Liberals and conservatives exhibit different cognitive styles and converging lines of evidence suggest that biology influences differences in their political attitudes and beliefs. In particular, a recent study of young adults suggests that liberals and conservatives have significantly different brain structure, with liberals showing increased gray matter volume in the anterior cingulate cortex, and conservatives showing increased gray matter volume in the in the amygdala. Here, we explore…

Background The default mode network (DMN) is a set of brain regions that exhibit synchronized low frequency oscillations at resting-state, and is believed to be relevant to attention and self-monitoring. As the anterior cingulate cortex and hippocampus are impaired in drug addiction and meanwhile are parts of the DMN, the present study examined addiction-related alteration of functional connectivity of the DMN. Methodology Resting-state functional magnetic resonance imaging data of chronic…
